How much yarn do you need for a crochet blanket?

A 50 × 60 in throw takes about 1,050–1,500 yards of worsted yarn in half double crochet, which is 9 skeins of 200 yards. Single crochet takes about 40% more, double crochet about 25% less, and thinner yarn needs more yards. Every yardage here is an estimate range: stitch pattern, tension, hook and fibre move it, so swatch first and buy from one dye lot.

How many skeins to buy

Take the high figure for your size, add 10%, and divide by the yards in one skein. For worsted half double crochet:

Crib53
Throw95

Read the yards on the label rather than assuming: the same weight of yarn can hold very different lengths. Buy every skein from the same dye lot, as colours can differ between lots.

A way to check your own number

  1. Crochet a swatch of at least 4 × 4 in (16 sq in) in your yarn and stitch.
  2. Weigh it in grams.
  3. Multiply by the blanket's area in square inches and divide by 16. A 50 × 60 in throw is 3,000 sq in, so 187.5 swatches.
  4. Divide by the grams in one skein, round up, and add one for safety.

Textured stitches such as waffle or bobble use more yarn than these tables. Crocheted fabric also uses more per square inch than knitted fabric in the same weight. The blanket size calculator handles knitting too; size options are in the blanket size chart.

Questions

How many skeins of yarn do I need for a blanket?

Divide the high yardage estimate by the yards in one skein, then add 10%. A 50 × 60 in throw in worsted half double crochet takes 1,050–1,500 yards: that is 9 skeins of 200 yards or 5 of 364 yards.

How many yards of yarn for a throw blanket?

About 1,500–2,100 yards in worsted single crochet, 1,050–1,500 in half double crochet and 750–1,200 in double crochet.

How much yarn for a baby blanket?

A 36 × 36 in baby blanket in worsted half double crochet takes about 454–648 yards.

Does yarn weight change how much I need?

Yes. Thinner yarn needs more yards: for the same stitch, DK takes about 1.3 times the yards of worsted and bulky about 0.7 times. Thicker yarn uses fewer yards but costs more per yard, so compare by total cost.

How can I check my own yardage?

Crochet a 4 in swatch in your yarn and stitch, weigh it, and multiply by the blanket's area divided by the swatch's area (16 sq in for 4 × 4 in). Then divide by your skein's weight to count skeins. Always buy the high end.

How much yarn for a blanket in grams?

Work it out in yards first, then divide by the yards per gram on the label (yards in the ball divided by its grams). Skeins of the same weight differ a lot in yards, so go by yards, not grams.
